Remarks.

Pfeiffer, who described this taxon from Cuming’s collection, did not state on how many specimens his description was based. The specimen found corresponds to Reeve’s figure, which was copied by Pilsbry (1898 [1897-1898]), who attributed this taxon to Reeve. Pilsbry classified the taxon with Neopetraeus Martens, 1885, but this is likely to be unjustified; Breure (1979: 136) treated it as a nomen inquirendum. Although the material is not accompanied by a taxon label in Pfeiffer’s handwriting, its type status is not disputed as the shell height agrees with Pfeiffer’s measurements. On the taxon label, the locality is given "Andes of Colombia"; on the front side of the card board is written ”Venezuela”. The latter locality has clearly been added during later years, and may reflect the change in political-administrative borders at that time. The protoconch sculpture is worn, making a definite conclusion difficult; judged from the colour pattern in this shell, this taxon may prove to belong to Drymaeus (Mesembrinus) .

Current systematic position.

Bulimulidae , Drymaeus (Mesembrinus) . Nomen inquirendum.
